Today my house had some issues with flooding (minor flooding, like a few thin puddles). Unfortunately one of these puddles formed under my computer. The computer isn't on the floor but my usb hub is. So, after trying to dry out the hub, I found that my mouse and ps3 controller are working normally, but my keyboard and wacom tablet are not. I have tried them on another PC and they worked, suggesting that my usb hub has been damaged. However, as I said, my mouse and controller are fully functional, and when I switch around the usb ports, my keyboard just won't respond (however, its leds work), even when directly in a usb port on the PC itself. Could this a motherboard bios issue? What can I do to diagnose it?
